IMPROVEMENT IN 'MACHINES FOR STRETGHING AND WINDING SILK THREAD.

T0 ALL WHOM IT MAY CONCERN:

Be it known that I. MICHEL CELLERIER, ot' Vthe city oi' Philadelphia, in the State of Pennsylvania, have invented a new and useful Machine for Stretching and Equalizing Silk Thread for the purpose of rendering it uniform after being twisted, while at the same time the winding i'nto a skein without its being removed from the machine is facilitated and I do hereby decla-rc the following to be a full and correct description. ci' the same, reference being had to the accompanying drawings, in whichi Figure l is a perspective view of the machine'eomplete.

Figures 2, 3, 4, 5, 6. are details'on an enlarged scale.

The object of this invention is the equaliziing and stretching or" silk thread so as to render it unifornraftcr being twisted. It consists in the application oi' a brake to the pulley of the spindle of the bobbin from which the thread is wound, for thc purpose of subjecting the thread to a uniform tension, and in the construction and arrangement of the rcel on to which thc thread is wound from the bobbin in a hank or skein of any desired length, without the removal oi` the reel or bobbin from the machine until the hank or skein is finished.

To enable others` to make and use this improved machine, I will'procced to describe its construction and operation, referring to the drawings, in which the .same part is marked by the same letter of reference wherever it occurs.

A marks the frame of the machine; B the main shaft, on the ond of which 1s the drivingpulley C, which receives motion from any suitable prime mover. `0n the main shaft may be any number of friction-pulleys, D E F, (see Eg. 6,) for driving a corresponding number of reels. On the further end of the main shaft is a pulley, G, which, by means of band II, drives pulley I, to the face of which` is attached the heart-shaped cam K. .The periphery of this cam works in contact with a small roller, a, let into the body of the lever L. This lever is pivoted at u to the frame of the machine. To its free end is attached cord ZJ, which passes up over pulley p', and is attached to the traverse bar M at b by a knot in the end of the cord. The bar M (see i'igs. l and 2) traverses on rollers, r1", placed in mortises in the upper ends of the front posts of the frame. A cord, c, is attached at c to the opposite end of bar M, and passes over pulley p, and has a wcigl1t,w, attached to its lower end. This'weight counteracts the lever L, 'and the two together operate the traverse-bar M. To this bar is attached any number of thread-guidcs, ."c, through which the thread to be wound runs, and. the reciproeating motion of the bai' distributes the thread uniformly on the surface of the reel on which it is wound. VN marks a rear cross-piece of the frame, from which project any number of arms or brackets, P I?, which support the shafts S of a corresponding number of reel pulleys, It. Only one of these pulleys R is represented in the drawing. It is driven by frictional contact with the surface of pulley E. To the face of pulley R is attached the reel It', (see iig. 8,) on which the'thread is to be wound. The rcel has a mortise,ff, into which is let a block, T, which lits it snugly, but so as to be easily removable. The outer face of block T corresponds in figure with the periphery of the reel It. The block is held in place by two buttons, d rl; it is easily removed, when the buttons are turned aside, by a blow applied through the hole c in the pulley It. Grooves z' t", in the rcel It and block T, air'ord a ready means of removing the block T in a radial direction. lU marks a trough, attached to the front of the frame and filled with water. In this trough are placed supports for the spindles Z, on which the bobbins V are fastened. On the bobbins V (see iig. is wound the twisted silk t which is to be stretched and equalized by theoperation of the machine. The spindle Z(see fig. 4) has a roller, m, on its end, to the surface ot' which is applied a friction-brake, (sec figs. l and 5,) formed by the lever W and its weight X. The thread t is carried up from the bobbin over the smooth glass edge g/ of the bar Y, and passed through guide z, and its free end attached to pin x in the face of pulley R. i

, The operation is as follows: The silk thread to be stretched and equalized is wound upon the bobbins V. These are fastened on thc spindles l, and placed in the trough U on the supports c in which the spindle turns, The trough is filled with water. The end of the thread t is carried up over the smooth edge y andV attached to the .pin z. Motion is now imparted to the main shaft, and the reel R revolves and winds oi the thread from the bobbin. The proper degree of tension is given to the thread by the brake-lever W and its weight X. The weight can be moved to any point on the lever that may be required to give the tension which is found necessaryfor each particular size of thread. The thread is evenly distributed on the reel by the vibration of the 6a, ma 2 bar M, 'which moves the thread-guide from the middle alternately to either side of the reel. When a reel has received the amount of thread required7 it is removed from the machine, and' an' empty one substituted for it. After the hunk or skein has dried upon the reel so as to prevent shrinking, the block 'l is removed, which slackens the thread upon the reel, and renders the removal of the skein or hunk easy. The effect of the operation is to stretch and equalize the threud after twisting, and render it uniform in quality. It is obvious that the machine is capable of indefinite extension longitudinally, and that :mindenite number of bobbins and reels can be operated on'the same machine in the'munner liereinbefore indicated. i

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, ,is-

1. In combination with u silk-reeling machine, constructed as described, an adjustable lever-brake applied to the pulley of the spindle which carries the bobbin from which the silk thread is reeled, for the purpose of Subjecting'the thread to a uniform tension, and thus equalizing its quality, as specified.

2. The removable friction-rcel R R', constructed, arranged, and operating as described.

The above specification of. my said invention signed and witnessed at Philadelphia this eighth day of December, A. D. 1866.
